LOG: [lldb][test] Increase polling frequency in ProcessAttach (#201532)

The test_attach_to_process_by_id_correct_executable_offset subtest
requires us to hit a breakpoint in an attached process. For this we
implement a loop that hits the breakpoint location every 2 seconds.

This patch increases the rate at which we hit this breakpoint to 50ms.
The reason is that a 2s interval means that this test is waiting on any
fast system for nearly 2 seconds on the first breakpoint hit. With a
50ms interval this subtest passed immediately.

Added:

    lldb/test/API/commands/process/attach/main.cpp

Removed:
